I searched but couldnt find anything but I was curious what octain you guys run? The gauge says premium only Ive been running the middle octain with ethanol but recently my plugs show signs of overheating or too low of octain just trying to narrow it down. thanks

 

93 Octane here.

 

diesel

 

Its Spelled Octane.

 

Ultra 94. Your plugs shouldn't be funny because of octane...the knock sensor should compensate even if you put in 87 by accident...

But 91 Octane is the recommended minimum on the H22a and H23a

 

94 plus octane boost

 

91 the highest they have around my area

 

94 octane from sunoco

 

91 is the highest here, I run that.

 

82 with mothballs and rc car gas
